Michigan lawmakers have introduced bills that would legalize unmanned red light cameras in the state.The bills, House Bill 4763 and 4762, were introduced May 22 by Reps. Wayne Schmidt, R-Traverse City, and Thomas Stallworth III, D-Detroit. The bills define running a red light that's caught on camera as a civil offense. That differs from a 2007 opinion from then-Attorney General Mike Cox, who said Michigan law recognizes red light running as a criminal violation, and the law was not authorized for photo ticketing.
